That list is a load of something a bull does without a toilet.

And of course, it touts its own oil.

0w-60 the most expensive? Really? Castrol TWS 10w-60 is IIRC about $11-$12/qt at a BMW dealer. 1/3 the price of synlube, and a proven oil to boot.

The best? I'd use M1 5w-50. Both API and ACEA rated, unlike the swill lube.
